Index Refresh

Keep wiki/index.md accurate and scannable. The index is the maintainer's first stop for navigation — its quality determines how cheap every subsequent operation becomes.

Inputs

• An operation issue with operationType: "index" (or the index-refresh routine title).
• The operation issue's target wikiId, spaceSlug, and space root. Refresh only that space unless the issue explicitly says this is a multi-space sweep.

Workflow

1. Read the target space's wiki/index.md as it currently stands.
2. Walk the target space's wiki/. wiki/projects/<slug>/standup.md entries are current-state companions for durable wiki/projects/<slug>/index.md pages; index them only as links attached to the matching project entry. Walk wiki/ by category (sources/, projects/, entities/, concepts/, synthesis/, plus any custom subdirectories the wiki schema added).
3. Read the target space's last ~50 entries of wiki/log.md to spot pages that were created or substantially changed but never made it to the index.
4. Per category, produce sorted entries of the form:

   - [[<path>]] — <one-line summary>

   The summary is one factual sentence pulled from the page's first paragraph or its title. No status, no datestamps in the index — those belong in the page itself or in the log.
5. Drop entries whose page no longer exists. Note the deletion in the log:

   ## [YYYY-MM-DD] index-refresh | reconciled
   - removed: [[wiki/old-page]] (page deleted)
   - added: [[wiki/new-page]] — <summary>

6. Add entries for pages that exist on disk but were missing from the index. Skip wiki/log.md and wiki/index.md themselves. For standalone wiki/projects/<slug>/standup.md without a matching durable project page, add it under Projects and flag it for later durable-page distillation.
7. Write project entries editorially. The Projects section should group work by the project's concept and purpose, not by issue ids, dates, statuses, UUIDs, or source metadata. Link task identifiers only as supporting evidence.
8. Preserve custom categories. If the wiki has added e.g. wiki/papers/ or wiki/runbooks/, keep its index section. Do not collapse to the default five categories.
9. Append a log entry with counts:

   ## [YYYY-MM-DD] index-refresh | added=N removed=M
   - operation issue: <issue identifier>

   If the index was already accurate, the log entry says added=0 removed=0 — still write it so future audits can see the run happened.

What this skill does NOT do

• Does not change page content.
• Does not resolve contradictions, fix broken links, or fill concept gaps. Those go to the next wiki-lint run.
• Does not write summaries that are not already supported by the page itself. If a page lacks a clear first paragraph to summarise, flag it for wiki-lint.

Voice

• Index entries are one factual line per page, present tense.
• No emojis, no statuses, no dates in wiki/index.md. Dates live in the log.

Verification

Before closing the operation issue:

• wiki/index.md matches the actual contents of wiki/ — no missing pages, no dangling entries.
• Project entries include current wiki/projects/<slug>/standup.md links when standups exist.
• Each index line has the form - [[path]] — <summary>.
• Custom category sections are preserved.
• wiki/log.md has the index-refresh entry with counts (even if the counts are zero).
• No page bodies were modified. No file under raw/ was modified.

Tools

wiki_search, wiki_read_page, wiki_write_page (for wiki/index.md and wiki/log.md only). Always include the operation issue's wikiId and spaceSlug.
